Our Airline Lubricator is exclusively designed to provide sufficient lubrication so as to ensure smooth working and prevent frictional wear on the piston. Due to insufficient oil which is frictional wear, the piston in the average Rock Drill reciprocates about 1600 to 2000 times per minute. Other internal parts move at corresponding rates, so frictional wear can be considerable. Friction produces heat and because of this factor it causes real trouble. Even with fine metallurgy, lack of oil can produce heat, it is enough sufficient to cause minute surface cracks that may result in complete breakage of the parts. So, it is suggested to use of Airline lubricators so as to overcome the problems.

Each Hava Rock Drill is made with great precision keeping in mind the smallest details so that it performs with the greatest reliability and power. Each spare part of the rock drill is made using only the best raw material and accurately machined on CNC Machines. These are perfectly heat treated and ground with the closest tolerance that are required for the best performance in the rock drill.

Just any other part will not do. Because you can not be sure of the quality, the material used, heat treatment and most important the tolerances, hence no substitute can ever be efficient or reliable for your Hava Rock Drill.

So don't compromise on quality and choose only genuine Hava spare parts for ur Rock Drill.
